UFC

Ronda Rousey says some "little punks" with a death wish broke into her home a few months ago and jacked everything from guns to Olympic rings and jewelry ... but her fiance tracked down the perps.

UFC fighter Sam Alvey is usually the one bringing the pain on the mat ... but he had the tables turned on him when he got choked out by a U.S. soldier in Iraq.

How did Nick Diaz respond Thursday after getting provisionally suspended by the UFC's drug-testing organization???

HE SMOKED WEEEEEEEEEED, SON!

Diaz fired up a fat joint with some friends in Vegas and didn't seem to have a care in the world after the U.S. Anti-Doping Agency (USADA) announced Nick accumulated 3 whereabouts failures over the last 12 months.

In other words, when USADA comes calling, you have to check in -- and Diaz didn't. Three times.

No word yet on how long the ban's gonna last ... but it's not lookin' good for Diaz -- who was suspended 18 months after a third failed drug test in 2015 (all for weed).

Diaz has 14 days to contest the violation ... if he wants to.

The last time we spoke with Dana White, he didn't seem too confident that either Diaz brother would ever fight again.

UFC rising star Robert Whittaker is hungry to fight the best, and Michael Bisping AIN'T IT -- even though he's the champ in their division.

The way Whittaker sees it, Bisping's fragile ass hasn't done much of anything since winning the middleweight belt last year ... so he and Yoel Romero are fighting to see who's really #1 at UFC 213.

"I want to fight the top of the food chain," Bobby Knuckles told TMZ Sports. "Bisping's out ... he hasn't fought a dude in the top 10 in a long time."

FYI: Bisping's only title defense was against 46-year-old Dan Henderson.

UFC badass Valentina Shevchenko is down to rumble with Ronda Rousey ... but don't get it twisted -- she's gotta put a beatdown on Amanda Nunes first.

Shevchenko told TMZ Sports the champ is getting SLEPT when they do the dance at UFC 213 ... Valentina says she's been training her ass off to avenge the L Nunes hung on her at UFC 196 -- and the new version of herself is too damn dangerous.

And once it's night-night for Amanda, Ronda can get hers -- if she wants it. Shev says that's up to her.

FYI, Rousey's kinda busy right now ... crushing obstacle courses on "Battle of the Network Stars."

Conor McGregor is gonna be PISSSSSED when he finds out how much cash Floyd Mayweather will make from their fight ... at least that's what Floyd's telling people.

One of those people is UFC champ Tyron Woodley -- who kicked it with Floyd at the Maxim 100 party in L.A. over the weekend.

In fact, Floyd made a video with Tyron calling him "the best UFC fighter" -- a compliment to Tyron and an obvious diss to McGregor.

Tyron co-hosted the "TMZ Sports" TV show (airs weeknights on FS1) and said Floyd was super cool during their hangout -- and even offered to give him some private fighting and business lessons.

Mayweather also mentioned McGregor ... telling Tyron, "Conor's gonna be pissed when he sees how much money I'm making."

UFC rising star Kevin Lee had no idea someone had pooped in the Octagon before his match with Michael Chiesa on Sunday until AFTER the fight ... and jokes, "There shoulda been a disclaimer!"

Lee (along with guest co-host Tyron Woodley) joined the guys on the "TMZ Sports" TV show and talked about Justine Kish soiling the mat in the fight before the main event.

UFC face-breaker Cyborg Justino is digging in for a fight in her battery case -- pleading not guilty to a misdemeanor charge for allegedly attacking another UFC fighter at an athlete retreat back in May.

Justino was cited for battery for allegedly punching Angela Magana in the face at the UFC center in Vegas on May 21 after she confronted Magana about comments on social media.

Video surfaced of the confrontation between the two -- and while you don't exactly see Cyborg connect with the punch, you can definitely hear it.

If convicted, Cyborg faces up to 6 months behind bars if the judge really wanted to throw the book at her. She's due back in court in August.

But she may have other problems. Magana told TMZ Sports she plans on suing the UFC star and has already met with a lawyer.

UFC fighter Felice Herrig is taking the high road in her now infamous fight with Justine Kish -- saying she refuses to "talk s**t" about her opponent ... despite what happened in the Octagon.

Herrig tells TMZ Sports she actually really likes Kish a lot and feels bad that she's blowing up in the media because of Sunday night's poo incident on live TV.

She actually calls for MMA fans to lay off Kish -- saying she's a really cool girl who doesn't deserve to be dragged through the mud.

The good news for Herrig ... she's already focused on her next fight and says she wants to avenge the only UFC loss on her record to one of the biggest stars in the sport.

A UFC fighter got the literal crap beat out of her Sunday night -- and left the proof INSIDE THE OCTAGON!!

The fighter is Justine Kish -- who was trying to wriggle her way out of a killer rear naked choke courtesy of Felice Herrig during "UFC Fight Night" in Oklahoma last night ... when her bowels betrayed her.

Kish lost the fight ... and the contents of her colon.

Michael Chiesa can't wait to shut up loudmouth Kevin Lee ... telling TMZ Sports he's gonna finish the designer label "dork" in Sunday's UFC main event.

Chiesa and Lee were the stars of a wild media event last month -- where Chiesa ran up on Lee for mentioning his mom... and got socked in the face.

MC's over the mama-drama, but told us he's PUMPED cause, "this time I get to ram my fist in his mouth and shut him up."

Chiesa knows a W moves him one step closer to Conor McGregor's lightweight belt ... AND wins his friends who bet on him a "butt-load of money" since Lee's the favorite.

UFC rising star Kevin Lee says Khabib Nurmagomedov is running scared ... and he's ready to expose the so-called #1 contender for Conor McGregor's lightweight belt.

Lee told TMZ Sports he's been gunning for Khabib forever ... but "the man just won't sign to fight."

Of course, Khabib's had his own issues -- he was hospitalized for a botched weight cut right before he was set to face Tony Ferguson at UFC 209. He was pulled from the fight and has been laying low ever since.

So, what's Lee's master plan? Beat Michael Chiesa -- who he's fighting this weekend at UFC Fight Night 112 -- so badly that Nurmagomedov has no choice but to throw down with him.

Lee's even got a deadline for Khabib ... but has serious doubts about him making the date.

"If he can't show up with six months notice then, God damn, I don't know what to do."

Nate Diaz's former agents claim they busted their ass to negotiate a sick multi-million dollar deal for him to fight Conor McGregor at UFC 202 only to get fired a month before the fight ... and now they're suing.

The Ballengee Group filed a lawsuit in District Court in Dallas claiming they had worked with Nate since 2014 and hammered out deals on several big fights including Rafael Dos Anjos, Michael Johnson and the first McGregor fight at UFC 196.

But Ballengee claims things got icy between the two sides in July 2016 -- right after sealing the deal for Nate to fight Conor at UFC 202 in August.

Ballengee claims Nate "unexpectedly" fired them -- and never paid them their cut for the UFC 202 fight, which was reportedly the biggest UFC pay-per-view ever at the time.

According to the suit, filed by attorney Jason Friedman, Ballengee is demanding more than $1 MILLION in damages.

We reached out to Nate for comment. So far, no word back.

"Sugar" Ray Leonard thinks Conor McGregor is a very tough dude -- but when it comes to his fight with Floyd Mayweather he has one piece of advice ... "DUCK!"

The boxing legend -- who beat Floyd's dad in 1978 -- was at LAX when he told us why he believes the Irish superstar is in for a beating when they face off on August 26.

Here's some nice, cool SHAAADE ... courtesy of Ice Cube.

As we previously reported, Cube's BIG3 basketball league is in a standoff with Mayweather, McGregor over the T-Mobile Arena for August 26.

BIG3 says it booked the venue first and won't budge (unless the price is right) -- while the boxing promoters aren't backing down either.

So, we asked Cube about the big fight when we saw him at LAX on Monday -- his response?

"Oh, that fight is uh happening?"

There's a fight of the century over the fight of the century ... with two major sporting events vying for the T-Mobile Arena on August 26th.

In one corner ... Mayweather vs. McGregor. When the fight was announced, Dana White and Floyd Mayweather stated it will take place at the Vegas venue.

Problem is ... Ice Cube's BIG3 basketball league already booked the location for the league championship game on the same night.

Our BIG3 sources tell us they have no plans to move -- they still have the venue booked and expect to play there on August 26th. The league even tweeted about it on Friday evening and T-Mobile has game tickets for sale on its site.

Sources connected to May-Mac tell us there are plans in motion to move BIG3 to the nearby MGM Grand Garden Arena ... it's just a matter of time before that becomes official.
